Tonkin Snub-nosed Monkey

The Tonkin snub-nosed monkey or Dollman's snub-nosed monkey (Rhinopithecus avunculus) is a slender-bodied arboreal Old World monkey endemic to northern Vietnam. It has black and white fur, a pink nose and lips, and blue patches around the eyes. It is found at elevations from 200 to 1,200 m (700 to 3,900 ft) on fragmentary patches of forest on craggy limestone areas. First described in 1912, the monkey was rediscovered in 1989 but is exceedingly rare. Out of the five snub-nosed monkey species in the world, the Tonkin snub-nosed monkey is the rarest. In 2008, fewer than 250 individuals were thought to exist, and the species was the subject of intense conservation effort. The main threats faced by these monkeys are habitat loss and hunting, and the International Union for Conservation of Nature has rated the species as "critically endangered".
